From the examples you've listed, the command tsNetGet was used to get the directory list. There's a setting "use_ssl" for FTPS explicit connection. However, ours is FTPS implicit connection. Nonetheless, I tried it but it failed, see code below. How can we set it to implicit connection? I listed below all the setting available for tsNetGet.

Going back to my inquiry - how to get the directory list on ftps with implicit connection on port 990. Based on the example, the setting for tsNetGet is "use_ssl", to Enable TLS for explicit FTPS. How about for implicit FTPS, what is command?
